Warning!!! If you do this procedure make sure that your computer and, calculator are connect. Use Ti Connect software and, make sure you can install the OS on the calculator without any interruption. At any time even at the very beginning of this process, if your computer or, calculator gets interrupted or you have a power failure during the installation of the OS, your calculator will be destroyed. So not attempt this procedure during a thunder storm.
You can use the Ti OS Downloader but, you will have no idea what OS is stored by the Ti OS Downloader. So, I suggest following my instructions and, installing the newest Ti 89 Titanium OS 3.10v.
Procedure to installing the newest Ti 89 Titanium OS 3.10v.
You can also get the latest copy of Ti 89 Titanium OS 3.10v by going to the Texas Instruments web site. You can get to that site instantly by clicking, "Ti 89 Titanium OS 3.10v." Once your at the Ti site click the Download Item, Ti 89 Titanium OS 3.10v. Next you can login or, click "continue as guest". I'd would click the "continue as guest". Once you have click, "continue as guest" the Ti 89 Titanium OS 3.10v. will download to you. Click, "SAVE". And then a folder will pop up. It is probably a folder that you download too. If so, you may want to change it and, "Save as" to this folder, "My Documents \ My TI Data \ Downloads". You can also go back and, download the Ti 89 Titanium guidebook too, if needed.
Link your computer and calculator with the USB cable or, Direct Black Link cable that came with the calculator.
Remove one of the AAA batteries. Press and hold the [APPS] key, and while holding the [APPS] key, replace the battery and turn the unit on. On the older TI-89 you should see "Press I to install code...", and you should press the  key to continue. But, on your Ti 89 titanium it should say, "Waiting to receive..." or, "Waiting to received OS...". Now you need to follow the instructions in the paragraph below to restore the calculator's operating system.
Next, drag the Ti 89 Titanium OS 3.10v. that you copied earlier to "My Documents \ My TI Data \ Downloads" out of that folder and, drop it in the "Ti Connect" icon on the desktop. Next the OS Downloader Warning will pop-up. Click, "OK" to continue and, the new OS will begin to install. The Ti Device window should pop up and, click on to the port where your Ti 89 Titanium is located, USB1 cable or Direct Black COM1. Just click, "Select" and, the OS will continue to download. Upon completion the newest Ti 89 Titanium OS 3.01v. will be installed.

Open up Device Manager.
Scroll to the USB controller and click the +. Turn the calculator ON then connect the USB cable to your PC. A new device will appear on the USB controller.
Right-click on the new device and, choose Update Driver Software. The Hardware Update Wizard will appear.
Choose "Browse my computer for driver software".
In the search field type in C:\Program Files\TI Education\Driver Files. Look for the tiehdusb.inf driver file.
Click on Next to finish installing the driver properly
Once the driver is installed click Finish.
Now click on the "Ti Connect" software on your desktop. Double-click the Ti Device Explorer located to the left inside the Ti connect window.
The software should start looking for your calculator. A pop-up should display looking something like what is pictured below. Under device your calculator should display. If your calculator is located the software will highlight on to it. Click, "Select" and another window should pop-up.
The next pop-up should look something like this. If your Ti 89 is present it will show up next to device and, probably won't say Titanium. Your cable type and port should be listed too.
If all the information is correct in the window that appears click "OK" and, you should be able to start downloading. You can skip the rest of the procedures. If your Ti 89 still won't connect to the computer goto Procedure 3 unless you have already tried Procedure 3, then goto procedure 4.
If the above procedure still does not help then try un-installing and, re-installing the Ti Connect software. After un-installing re-boot your computer. After re-booting your computer you can get the latest copy of Ti Connect software by going to the Texas Instruments web site. You can get to that site instantly by clicking, "Ti Connect software" At this Ti site under "View: Connectivity Software", Click, "the OS link that applies to your computers operating system". Next, click the Download Item, "Ti Connect software for ....OS". Next you can login or, click "continue as guest". I'd would click the "continue as guest". Once you have click, "continue as guest" the Ti Connect software for ....OS will be download to you. Click, "Save" and then a folder will pop up. It is probably a folder that you download too. If so, you may want to change it and, 'Save as" to this folder, "Desktop."
Next right-click the Ti Connect executable on your desktop and select, "Properties." Then click the "Compatibility" tab located at the top of the "Properties" window. Click the box next to "Run this program in compatibility mode for." and select "Windows XP Service Pack 2" from the drop-down menu. Click "Apply" and choose "OK." Double-click the TI Connect executable and select "Next" to begin the installation. Click "Yes" to OK the installation process to proceed. Then click "Finish" to complete the installation. Next, reboot your computer.
Now go back and try Procedure 1 and 2 again. If you have already tried Procedure 1 and 2 twice, go to Procedure 4.
If the above procedures fail then try a different cable and if possible a different computer.
If trying different cables/computers fails, please contact and fill out a Ti Cares Customer Assistance Form. You can get there by clicking this link, " Ti Cares Customer Assistance Form "
